“错误：意外，请重试”与 GoogleBigQuery JOIN

Question

我知道这是 Google BigQuery 的一个较早的问题，但似乎该问题已在 2013 年中期得到解决。我想知道最近几个月是否有针对此问题的任何解决方法/修复。这是我从 google 示例数据中查询的结果。

SELECT publicdata:samples.natality.mother_age, publicdata:samples.gsod.station_number
FROM [publicdata:samples.natality]
INNER JOIN [publicdata:samples.gsod]
ON publicdata:samples.gsod.year = publicdata:samples.natality.year
LIMIT 100

Query Failed
Error: Unexpected. Please try again.

Answer 1

感谢您的报告！应该改进该错误消息。

与此同时：使用表别名的相同查询运行良好（尽管我不得不将 JOIN 更改为 JOIN EACH 以处理两个表的大小）。

代替：

SELECT publicdata:samples.natality.mother_age, publicdata:samples.gsod.station_number
FROM [publicdata:samples.natality]
INNER JOIN [publicdata:samples.gsod]
ON publicdata:samples.gsod.year = publicdata:samples.natality.year
LIMIT 100

做：

SELECT a.mother_age, b.station_number
FROM [publicdata:samples.natality] a 
INNER JOIN EACH [publicdata:samples.gsod] b
ON a.year = b.year
LIMIT 100
